+* **Added support for representing buses in EAL**
+
+  A new structure ``rte_bus`` is introduced in EAL. This allows for devices to
+  be represented by buses they are connected to. A new bus can be added to
+  DPDK by extending the ``rte_bus`` structure and implementing the scan and
+  probe functions. Once a new bus is registered using provided APIs, new
+  devices can be detected and initialized using bus scan and probe callbacks.
+
+  With this change, devices other than PCI or VDEV type can also be represented
+  in DPDK framework.
+
 * **Added generic EAL API for I/O device memory read/write operations.**
 
   This API introduces 8-bit, 16-bit, 32bit, 64bit I/O device
